：使用资源组进行精细化资源控制

资源组授权的工作原理

您可以使用资源组（Resource Group）对阿里云账号内的资源进行分组管理。例如，为不同的项目创建对应的资源组，并将资源转移到对应的组中，以便集中管理各项目的资源。更多信息，请参见什么是资源组。

在完成资源分组后，您可以为不同的RAM授权主体（RAM用户、RAM用户组或RAM角色）授予指定资源组范围的权限，从而限定这个授权主体只能管理该资源组内的资源。更多信息，请参见资源分组和授权。

这种授权方式的优点有：

• 权限精细化：确保每个身份能获得最准确的资源访问权限，避免账号下的多个项目的资源混合管理。

• 良好的扩展性：后续新增资源时，只需将其加入该资源组，RAM身份便会自动获得新资源的相应权限，无需再次授权。

为RAM用户授予资源组级别的权限

下面以RAM用户为例，介绍授予指定资源组内数据灾备资源权限的操作步骤。

支持资源组的资源类型

数据灾备支持资源组的资源类型如下表所示：

不支持资源组级别授权的操作

数据灾备中不支持资源组级别授权的操作（Action）如下：

对于不支持资源组授权的操作，授权时资源范围选择资源组级别将无效。如果仍需要RAM用户有上述操作权限，您需要创建自定义权限策略，授权时资源范围选择账号级别。

以下是两个自定义权限策略示例，您可以根据实际需要调整策略内容。

• 允许不支持资源组级别授权的全部只读操作：Action中列举不支持资源组级别授权的所有只读操作。
